(Adopted by the General Assembly of the Association in Grenoble, 1975, and amended by the General Assemblies in Melbourne, 2011 and Prague, 2015 and by the Scientific Assembly in Kobe, 2017.)


I. Objectives of the Association

  1. The International Association of Seismology and Physics of the Earth's Interior (IASPEI) is a non-governmental and non-profit organisation with the purposes:

    a. To facilitate: research on theoretical, observational and applied seismology, such as the propagation of seismic waves; the discussion, design and adoption of standards for observatory practice and data storage; and generally all matters related to seismology.

    b. To promote multidisciplinary research related to earthquake science, internal structure, properties and processes of the Earth

    c. To initiate and coordinate the conduct and communication of related research which depends on co-operation between different countries.

    d. To organise and support international conferences and meetings focusing on the above-mentioned topics and to support, including financially if the budget allows, the participation in such meetings of young researchers and of scientists from developing countries.

II. Members of the Association

  1. Each country having adhered to the International Union of Geodesy and Geophysics (IUGG) is a member.
  2. Each scientist participating in IASPEI activities and in the Scientific Assemblies is an individual IASPEI member. Any member attending the General Assemblies or participating in other activities of the Association at least once in the past ten years is considered to be an active individual member.

III. National Committees

  1. Each National Committee for the IUGG (or national organisation adhering to IUGG) where possible should nominate a section, or sub-committee, for Seismology and Physics of the Earth's Interior. The functions of this section or sub-committee are to facilitate and co-ordinate in their respective countries the study and practice of Seismology and Physics of the Earth's Interior, in accordance with the objects of the Association. Each National Committee and the Section or Sub-Committee shall be empowered to refer to the Association matters for discussion falling within the competence of the Association.
  2. The National Committee (or adhering organisation) names in each country a correspondent (hereafter National Correspondent), whose duty is to provide liaison between IASPEI and the Section in each country.
  3. The National Committee, on the recommendation of the Section or Sub-Committee, nominates the delegate or delegates who shall represent it at the General Meeting of the Association. One of these delegates shall be designated as the principal delegate of the country and shall cast the vote of that country whenever a "national vote" is required (refer section VIII.2). If a National Committee does not formally appoint a delegate, the (older in age in case of two) National Correspondent(s) present at the General Meeting is the principal delegate.
  4. Official communications sent by the International Association of Seismology and Physics of the Earth's Interior to an adhering country shall be addressed to that country's IASPEI National Correspondent or, in default, to its National Committee for the IUGG.
